Alright, I had to create an account because I wanted my voice to be heard on this.
PLEASE use something other than WMV. I have a Mac (and as far as my household goes, I don't have access to a PC) and I would love to have either MP4 or MKV, if that works on Mac *natively*. If not, then please consider posting MP4 from now on!
I could not get VLC running on my Mac, even after consulting forums and how-to manuals. VLC is not an option...
WMV runs okay on Mac, thanks to a nice, free plug-in called "Flip4Mac", but basically the Mac is a walled garden to every extent. MP3, MP4, AAC, and Apple Lossless ONLY. :-/
As a matter of fact, I've been getting increasingly frustrated with how hobbled I am on Mac and am considering a high-end Sony Vaio Laptop to replace my 15" MBP after 6+ years on Mac.
